    Image translation for single-shot focal tomography. Optica 2(9):822–825, September 2015.
    Focus and depth of field are conventionally addressed by adjusting longitudinal lens position. More recently, combinations of deliberate blur and computational processing have been used to extend depth of field. Here we show that dynamic control of transverse and longitudinal lens position can be used to decode focus and extend depth of field without degrading static resolution. Our results suggest that optical image stabilization systems may be used for autofocus, extended depth of field, and 3D imaging.
    The authors have used a 17-ch MMDM with tip-tilt stage (MMDM15-17TT).

    Modal-based phase retrieval for adaptive optics. J. Opt. Soc. Am. A 32(6):1160–1170, June 2015.
    Optical aberrations have detrimental effects in multiphoton microscopy. These effects can be curtailed by implementing model-based wavefront sensorless adaptive optics, which only requires the addition of a wavefront shaping device, such as a deformable mirror (DM) to an existing microscope. The aberration correction is achieved by maximizing a suitable image quality metric. We implement a model-based aberration correction algorithm in a second-harmonic microscope. The tip, tilt, and defocus aberrations are removed from the basis functions used for the control of the DM, as these aberrations induce distortions in the acquired images. We compute the parameters of a quadratic polynomial that is used to model the image quality metric directly from experimental input–output measurements. Finally, we apply the aberration correction by maximizing the image quality metric using the least-squares estimate of the unknown aberration.

It is known that an on-axis spherical/parabolic optical component, placed at an angle to the incident beam introduces defocus as well as astigmatism in the image plane. Although the former can be compensated by changing the focal plane position, the latter cannot be removed by mere optical realignment. Since the DM is to be used to compensate a turbulence-induced curvature term in addition to other aberrations, it is necessary to determine the aberrations induced by such (curved DM surface) an optical element when placed at an angle (other than 0\&\#xA0;deg) of incidence in the optical path. To this effect, we estimate to a first order the aberrations introduced by a DM as a function of the incidence angle and deformation of the DM surface. We record images using a simple setup in which the incident beam is reflected by a 37 channel micro-machined membrane deformable mirror for various angles of incidence. It is observed that astigmatism is a dominant aberration, which was determined by measuring the difference between the tangential and sagittal focal planes. We justify our results on the basis of theoretical simulations and discuss the feasibility of using such a system for adaptive optics considering a trade-off between wavefront correction and astigmatism due to deformation.",

    	address = "Enschede",
    	abstract = "In this thesis we describe the development of a new class of optical components to enhance the imaging performance by enabling adaptations of the optics. When used at extreme ultraviolet (EUV) wavelengths, such ?adaptive optics? offers the potential to achieve the highest spatial resolution in imaging known to date, i.e., a resolution down to several nanometers. These optics are discussed, e.g., in the field of photolithography for the fabrication of more energy efficient and faster electronic equipment. The topics in this thesis can be subdivided into two parts. The first part includes a mirror design that can be used to enhance the spectral quality of EUV light sources. Our design consists of a diffractive Fresnel zone plate patterned in the surface of a curved mirror to achieve spectral purification, i.e., removing undesired wavelengths of the EUV light sources. The removed light is recycled to produce more EUV light. This design achieves four orders of magnitude purification and provides a 35% improvement in efficiency. The second part of the thesis describes a new class of adaptive multilayer mirrors that can be used to correct wavefront distortions, reflectance degradations or wavelength deviations. These adaptive optics contain integrated crystalline piezoelectric thin films of which the film thickness can be adjusted by an externally applied voltage. Because the optics substrates typically have an amorphous structure, so far it was not possible to grow high quality crystalline piezoelectric films on them. We utilized crystalline nanosheets on these substrates to grow the highest quality, i.e., epitaxial, piezoelectric films (PbZr0.52Ti0.48O3, PZT). The PZT films show a record high piezoelectric coefficient of 98 pm/V, although the piezoelectric response in this case is still reduced due to clamping by the substrate. We minimized the clamping effect by depositing films with a columnar structure, which enhances the voltage-controlled change in film thickness. In these films we measured a piezoelectric response of 280 pm/V, the highest value reported on glass substrates. Importantly, the developed films can produce a stroke of 25 nm. This order of magnitude is useful when considering to correct EUV wavefront distortions.",

In this method, Fermat’s principle and matrix methods are used to describe the optical path of the entire optical system with a shift object plane and a fixed corresponding image plane in the carrier coordinate system. A constant optical path length is determined for each ray set, so the correspondence between the object and the shift free image point is used to calculate the solution to the points on the surface profile of the deformable mirrors (DMs). Off-axis three-mirror anastigmats are used to demonstrate the benefits of optical image stabilization with one- and two-deformable mirrors.",

In this thesis, an introduction to the state of myopia research is given first, with particular reference to studies of accommodation and higher-order ocular aberrations, which feature in the subsequent chapters. Following a brief introduction to the general technique of aberrometry and visual stimulus control using adaptive optics, the development of a monocular adaptive optics instrument for this purpose is described. The instrument is used to vary a dioptric stimulus and record the accommodation response in pilot studies and a detailed experiment, which has also been published elsewhere. It is found, among other things, that accommodation can respond to more than one different input level during its latency period, and that such inputs can be stored until components of the accommodation control system are free to process them. Indications of a minimum halting time for accommodation, of around 0.6 s, are presented. In later chapters, the development and testing of a new, binocular adaptive optics apparatus will be found. As well as binocular aberrometry and adaptive optics control of stimulus aberrations, this instrument displaces images to allow for and stimulate ocular convergence in binocular accommodation experiments. It is the first instrument in the world with its combined functionalities. Finally, the contribution of this thesis is summarised, and further instrumentation development and experiments are put forward for the continuation of this branch of accommodation and myopia research.",

    Interferometric velocity measurements through a fluctuating gas-liquid interface employing adaptive optics. Opt. Express 21(25):30653–30663, December 2013.
    Optical transmission through fluctuating interfaces of mediums with different refractive indexes is limited by the occurring distortions. Temporal fluctuations of such distortions deteriorate optical measurements. In order to overcome this shortcoming we propose the use of adaptive optics. For the first time, an interferometric velocity measurement technique with embedded adaptive optics is presented for flow velocity measurements through a fluctuating air-water interface. A low order distortion correction technique using a fast deformable mirror (MMDM15-17TT) and a Hartmann-Shack sensor (based on piA640-210gm) with high frame rate is employed. The obtained high control bandwidth enables precise measurements also at fast fluctuating media interfaces. This methodology paves the way for several kinds of optical flow measurements in various complex environments..

    Adaptive optics combined with computer post-processing for horizontal turbulent imaging. In Real-Time Image and Video Processing 8437. 2012, 84370Y-84370Y-9.
    We describe an approach that offers an almost real time image enhancement through turbulent and wavy media. The approach consists in a combination of optimization-based adaptive optics with digital multi-frame post-processing. Applications in astronomical and terrestrial imaging, where the image features are initially unresolved due to loss of contrast, blur, vibrations and image wander have been illustrated by experimental results. A new software from Flexible Optical BV is presented..

    Physical and mechanical properties of a TIR-based liquid micro deformable mirror. In Micro-Optics 8428. 2012, 84281W-84281W-11.
    A deformable mirror based on the principle of total internal reflection (TIR) of light from an electrostatically deformed liquid-air interface was realized and used to perform closed-loop adaptive optical correction on a collimated laser beam aberrated by a rotating phase disk. The liquid system was characterized including open- and closed-loop frequency responses, determination of rise-times, the damping times of the liquid, and the influence of liquid surface motion in the absence of external optical aberrations. The dynamic behavior of the liquid was found to be dominated by gravity waves and the results of the experimental realization were in good agreement with the predictions of the theory. A miniaturization of the system promises to eliminate the dominant gravity waves and considerably reduce the errors introduced by ambient vibrations. Here we explore the possibilities of such a micro mirror and establish the boundary conditions and requirements for its realization..

    Speckle imaging through turbulent atmosphere based on adaptable pupil segmentation. Opt. Lett. 36(14):2656–2658, July 2011.
    We report on the first results to our knowledge obtained with adaptable multiaperture imaging through turbulence on a horizontal atmospheric path. We show that the resolution can be improved by adaptively matching the size of the subaperture to the characteristic size of the turbulence. Further improvement is achieved by the deconvolution of a number of subimages registered simultaneously through multiple subapertures. Different implementations of multiaperture geometry, including pupil multiplication, pupil image sampling, and a plenoptic telescope, are considered. Resolution improvement has been demonstrated on a ~550 m horizontal turbulent path, using a combination of aperture sampling, speckle image processing, and, optionally, frame selection..

    Imaging through turbulence with temporally and spatially multiplexed systems. In Optics in Atmospheric Propagation and Adaptive Systems XIV 8178. 2011, 81780F-81780F-8.
    Based on the analysis of factors that influence atmospheric imaging over long turbulent horizontal paths, we consider a number of practical configurations of opto-electronic surveillance systems with optimized performance. Our approach is based on simultaneous quasi real-time processing of a number of images obtained through uncorrelated atmospheric paths, using either temporal or spatial multiplexing. Practical results obtained on a 4.25 km imaging path using newly developed imaging system, based on temporal multiplexing, combined with image restoration based on projection on convex sets, are reported. Potential applications include optical and IR long-range security and military surveillance, unmanned aircraft imaging systems and naval optical imaging and warning systems..

    By analysis of the mechanical equations, describing deformable mirrors, we show that the print-through is the natural property of a deformable mirror, which is completely defined by the geometry and mechanics of deformation. The print-through causes increased scattering in imaging applications, and can result in hot/cold spots in laser applications. Further development of adaptive optics for extreme UV applications would also require to address the print-through problem. We describe different ways to reduce, or completely eliminate the print-through in continuous faceplate and membrane deformable mirrors. In combination with simple hysteresis compensation, our approach allows for high-precision feedforward control of these deformable mirrors, directly in terms of Zernike modes..

    The visible second harmonic of the idler output from a noncollinear optical parametric amplifier was compressed using adaptive dispersion control with a linear deformable mirror from Flexible Optical B.V. The amplifier was pumped by and seeded in the signal path by a common 400nm second-harmonic pulse from a Ti:sapphire regenerative amplifier. Thus, both the idler output and the second harmonic of the idler were passively carrier-envelope phase stabilized. The shortest pulse duration achieved was below 3fs..

    Experiments on speckle imaging using projection methods. In Unconventional Imaging, Wavefront Sensing, and Adaptive Coded Aperture Imaging and Non-Imaging Sensor Systems 8165. 2011, 81650M-81650M-10.
    We present some experimental results of speckle imaging for near-diffraction-limited observation of ground-based scenery and astronomical objects through atmospheric turbulence. The method of alternating projections onto convex sets is used for iterative reconstruction of the point-spread function (PSF), combined with Wiener filtering for deconvolution and several pre-processing techniques. A modification of the optical system with aperture segmentation is considered. The results of imaging on a horizontal path and astronomical imaging are reported and compared with time averaged and best frame images. Apparent image improvement is demonstrated in a field much wider than the isoplanatic patch size..

    Emission of spiral patterns from filaments in the infrared. Opt. Express 18(23):24258–24263, November 2010.
    The authors investigated the spectral and spatial properties of the supercontinuum emission of single filaments in air in the infrared (1.5 µm - 5.3 µm). The infrared emission of the filament was controlled by modulating the spatial phase of the femtosecond driver pulse with a deformable mirror. Filaments with a characteristic spiral emission pattern in the infrared were generated for a variety of different wavefront profiles of the femtosecond pulse. The properties of this novel class of emission were analyzed more closely. Further understanding of the corresponding emission dynamics of the filament will help to refine current models of filament propagation. The author have used 37-ch 30mm PDM from Flexible Optical B.V..

    Model-based aberration correction in a closed-loop wavefront-sensor-less adaptive optics system. Opt. Express 18(23):24070–24084, November 2010.
    This paper presents an aberration correction approach for WFSless AO systems based on the model of the WFSless AO system and a small number of intensity measurements, where the model is identified from the input-output data of the WFSless AO system by black-box identification. This approach is validated in an experimental setup with 20 static aberrations having Kolmogorov spatial distributions. The setup uses 37-ch PDM from Flexible Optical B.V..

    Optical design of a variable view imaging system with the combination of a telecentric scanner and double wedge prisms. Appl. Opt. 49(2):239–246, January 2010.
    Recent developments in micro-electro-mechanical systems and biotechnology have presented an emerging need for observation of dynamic targets in three-dimensional space. Unfortunately, conventional microscopes with fixed optical parameters have difficulty supplying sufficient vision information because of occlusion, small field of view, and low depth resolution. This paper introduces the design of a variable view imaging system that can supply a flexible view with a relatively large zenith angle and simple kinematics. Because of several performance factors, a multiobjective optimization process is applied to achieve an appropriate design. A prototype system is developed and used to verify the proposed design. The authors have used 37-ch "OKO" deformable mirror..

    The Naval Postgraduate School is developing a laboratory environment for testing advanced beam control methods for compensation of atmospheric turbulence in adaptive optics for use in a maritime environment. This paper presents a multichannel transverse adaptive filter for beam control. Adaptive filters are useful for such control due to the constantly changing nature of atmospheric turbulence. A multichannel filter is required due to the multiple deformable mirror input commands and wavefront sensor output measurements in the system.

    Effect of correction of ocular aberration dynamics on the accommodation response to a sinusoidally moving stimulus. Opt. Lett. 34(21):3274–3276, November 2009.
    The authors used an adaptive optics system to correct the aberration dynamics of five subjects while they fixated on a monochromatic stimulus undergoing sinusoidal vergence changes between 1.5 and 2.5 D, at a temporal frequency of 0.2 Hz. The aberrations were measured at 20 Hz using a Shack-Hartmann sensor and corrected using a 37-actuator deformable mirror. The accommodation response (AR) was analyzed in terms of the gain and phase lag. Manipulation of aberrations significantly affected the gain of the AR for only one subject when the odd-order aberrations were corrected. The predictability of the sinusoidal stimulus could account for the lack of an effect in the remaining subjects and conditions. A 37-actuator piezoelectric deformable mirror from Flexible Optical B.V. was used to manipulate the aberrations in real time..

    Adaptive optics for enhanced signal in CARS microscopy. Opt. Express 15(26):18209–18219, December 2007.
    The authors report the use of adaptive optics with coherent anti-Stokes Raman scattering (CARS) microscopy for label-free deep tissue imaging based on molecular vibrational spectroscopy. The setup employs the 15-mm 37-channel deformable membrane mirror and a random search optimization algorithm to improve signal intensity and image quality at large sample depths. The authors demonstrate the ability to correct for both system and sample-induced aberrations in test samples as well as in muscle tissue in order to enhance the CARS signal. The combined system and sample-induced aberration correction increased the signal by an average factor of ~3x for the test samples at a depth of 700 µm and ~6x for muscle tissue at a depth of 260 µm. The enhanced signal and higher penetration depth offered by adaptive optics will augment CARS microscopy as an in vivo and in situ biomedical imaging modality..

Unlike previous work combining adaptive optics and laser machining the authors use the machining outcome itself as the fitness parameter for the optimization procedure. Single-pulse ablation features with programmable aspect ratios and dimensions as small as 2.5 µm are faithfully reproduced by the technique in a chromium-on-glass test sample..

    Adaptive wavefront correction in two-photon microscopy using coherence-gated wavefront sensing. Proceedings of the National Academy of Sciences 103(46):17137-17142, 2006.
    The authors demonstrate that resolution and signal size in two-photon microscopy can be substantially improved, even in living biological specimens, by adaptive wavefront correction based on sensing the wavefront of coherence-gated back-scattered light (coherence-gated wavefront sensing, CGWS) and wavefront control by a deformable mirror. A nearly diffraction-limited focus can be restored even for strong aberrations. CGWS-based wavefront correction should be applicable to samples with a wide range of scattering properties and it should be possible to perform real-time pixel-by-pixel correction even at fast scan speeds. The adaptive optics closed loop system uses a 37 actuator OKO membrane deformable mirror..

    Feedback interferometry with membrane mirror for adaptive optics. Optics Communications 218:33-41, 2003.
    Feedback interferometers can be used for many optical measurements as well as aberration correction. The choice of the phase modulator in the interferometer has major influence on the operation of the feedback system. Conventional wisdom is that independent actuator movement is a basic requirement for the modulator in order to allow the feedback system to operate in stable fashion and that membrane mirrors are not suitable. We demonstrate the operation of a feedback interferometer which uses a membrane mirror as the phase modulator. We show that even with the strong coupling introduced by the influence function of the membrane mirror, the feedback system can still operate normally. Our interferometer is based on a radial shearing polarizing Sagnac interferometer. The current system is able to correct static aberration with significant improvement on Strehl ratio..

    Cryogenic wavefront correction using membrane deformable mirrors. Opt. Express 8(1):17–26, January 2001.
    Micro-machined membrane deformable mirrors (MMDMs) are being evaluated for their suitability as wavefront correctors at cryogenic temperatures. Presented here are experimental results for the change in the initial mirror figure of 37-channel MMDMs from OKO Technologies upon cooling to T=78K. The changes in the influence functions are also explored. Of the sample of 3 mirrors tested, one was found to have sufficiently small initial static aberrations to be useful as a wavefront corrector at this temperature. The influence functions at T=78K were found to be similar in shape to both those at room temperature and theoretical predictions of the MMDMs surface shape. The magnitude of the surface deflection at T=78K was reduced by around 20% compared with room temperature values..

    Pulse compression by use of deformable mirrors. Opt. Lett. 24(7):493–495, April 1999.
    An electrostatically deformable, gold-coated, silicon nitride membrane mirror was used as a phase modulator to compress pulses from 92 to 15 fs. Both an iterative genetic algorithm and single-step dispersion compensation based on frequency-resolved optical gating calibration of the mirror were used to compress pulses to within 10% of the transform limit. Frequency-resolved optical gating was used to characterize the pulses and to test the range of the deformable-mirror-based compressor..
